Conventional and Non-Conventional Sources of Energy
1. Conventional Sources of Energy
Conventional energy sources are those that have been used for a long time and are typically derived from fossil fuels and nuclear power.
- Coal: Widely used for electricity generation and industrial processes.
- Oil: Primarily used in transportation, heating, and electricity generation.
- Natural Gas: Increasingly used for electricity generation and heating due to its lower carbon emissions compared to coal and oil.
- Generated through nuclear fission in power plants, providing a significant amount of electricity with low greenhouse gas emissions.
2. Non-Conventional Sources of Energy
Non-conventional energy sources are those that are renewable and considered more sustainable, contributing to environmental conservation.
- Harnessed from sunlight using photovoltaic cells and solar thermal systems. Increasingly popular due to falling costs and government incentives.
- Generated through wind turbines that convert wind kinetic energy into electricity. Significant potential in coastal and open areas.
- Produced from flowing or falling water, typically through dams. Renewable and reliable but can have environmental impacts on aquatic ecosystems.
- Derived from organic materials like agricultural waste, wood, and animal waste. Used for cooking, heating, and electricity generation.
- Sourced from the heat stored beneath the Earth's surface. Used for electricity generation and direct heating applications.
- Harnessed from ocean tides and waves, though still in the experimental stages in many regions.
